Diodes, rectifiers, and arrays are some of the most common components found in the electronics industry. The applications for these components are varied, ranging from power supplies and rectifiers to switching circuits and other analog and digital signal processing applications. In this article, we will explore the MSRT200120(A)D application field and working principle.

The MSRT200120(A)D, also known as an avalanche diode, is an array of closely spaced, high voltage diodes connected in series. The series configuration enables the diodes to work together to ensure that any transient overloads of current or voltage are evenly divided between the diodes and thus shared among them. This feature of avalanche diodes makes them extremely attractive for use in circuits that require high operating voltages, as they allow the design engineer to use standard series connected diode arrays without the risk of excessive current through any one diode.

The MSRT200120(A)D is rated for operation up to 500V and its maximum avg. forward current is 2A. It can also be used up to several thousand volts with an appropriate series resistor. The rating for each diode within the avalanche array is 200V and can handle up to 1A of current.

The most common applications for the MSRT200120(A)D include power supplies, motor control and over-voltage protection. It is also used in snubber circuits and in switching applications where a low resistance connection between two points is required. In power supplies, the avalanche diode array provides a fast response to voltage surges and spikes and prevents damage to sensitive components due to over-voltage. In motor control, the avalanche array helps limit inrush currents and improves the efficiency of the operation. Finally, in over-voltage protection, the avalanche array prevents excessive voltage from reaching the load end of the circuit, thereby protecting the load from damage.

The working principle of an avalanche diode array is based on the avalanche effect, which is a phenomenon whereby a sudden increase in voltage causes a large number of electrons to suddenly become free and flow from one materials to another. This effect is beneficial in certain applications, as it ensures that the amount of current that passes through a particular diode or component is limited. It also prevents excessive current from flowing in the circuit, which can be damaging to sensitive components or lead to malfunctions.

The avalanche effect occurs when a material is subjected to a large potential difference and the electric field between two electrodes raises significantly. This increased electric field causes the electrons to become "unconfined" from their atoms and accelerate, allowing them to cross a barrier of a higher energy level. The electrons then impact other atoms and quickly create more electrons, creating a chain reaction that amplifies the current.

In avalanche diode arrays, the avalanche effect is used to ensure that a sudden increase in voltage or current is evenly distributed between the diodes, instead of having all the energy concentrated in a single diode. This prevents excessive current from flowing in any single diode, which can cause damage to the component or the circuit as a whole. In addition, it ensures that the avalanche diodes can handle high voltage and current spikes, providing greater reliability and efficiency for the circuit.

The MSRT200120(A)D avalanche diode array is often rated for operation up to 500V, however, it can be used at even higher voltages with the addition of an appropriate series resistor. The avalanche array is often used in power supplies, motor control, over-voltage protection, snubber circuits, and switching applications. Its ability to evenly divide the current among the diodes and provide fast response to voltage or current spikes make it an ideal component for these applications.
